Noob Questions: Firmware,Bootloader, root.

Hi, i just got the moto g5 plus, i always have phones that from the moment i bought them they wouldn recive any updates, so i realy didnt care if unlocking the bootloader installing new recoverys will affect the OTA updates. So i have a couple of questions.
1- first i want to at least have a stock firmware just in case, but i cant figure out which one should i download from here
firmware.center/firmware/Motorola/Moto%20G5%20Plus/Stock/
Before i always use sammobile.com and it was really easy to found a stock firmware from Argentina. My compilation number is: npns25.137-15-11 this means that i suppose to download that one XT1681-XT1683_POTTER_BRASIL_LATAM_MEXICO_7.0_NPN25.137-15_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip ?
2- it is possible to unlock the bootloader and root your phone without installing a new recovery? i was reading some post and when you change your recovery or you modify something the OTA update will stop working. they are some methods like the magisk but they seem i little bit too complex for me and i don't want to do it every time that a new update is available.
thanks for the help, and sorry for my English i am from Argentina.

1. yes, but any build will flash and run, so it doesn't really matter that much...
2. Nope. You need to flash TWRP in order to root. This is because the stock recovery will only flash signed images... You can use Magisk, after backing up a stock build. Anytime there is an OTA, just restore to that system image, Flash the original recovery via fastboot, and then take the OTA. Once you have it, flash TWRP again, and restore to your other build. Or just run a custom room like Lineage or RR, and this whole thing isn't really an issue anymore.

yeah i know i had a samsung galaxy s3 until now, and i always have cyanogen, slimrom or now lineage, but this is the first device that i have one that will get updates (at least 1 more :S) and i want to seize that
i will start downloading that file just in case
1- ok so unlocking the bootloader doesn't affect updates only when you modify files? when the update is installing is basically comparing the files that you have with the ones that you suppose to have and if there is something different it will fail? its something like that?
2-dumb question how do you do a full backup in the stock recovery there is no option no do a nandroid backup or it will appear after i just unlock the bootloader?

Bootloop

Hey everyone I just flashed the stock ROM on my device and just after that I got the update, when I clicked onto update my device just got moved to TWRP and didn't flashed the update too and finally the main issue is that my device just stuck in the TWRP. When I turn on my device It directly loads to the TWRP, I need to go to bootloader menu and then hit start to turn on my device.
Could anyone tell me how to solve this issue??

Can't auto process 'stock' OTA updates with custom recovery. Must use stock recovery plus meet several other prerequisites that are difficult to satisfy on a rooted/modded device. Best option is to restore the nandroid you made before updating. What, no backup?? Reinstall stock image and hope for the best.

Help with soft brick

Hi guys,
I got the ASUS Zenfone 3 Zoom and started playing with it. Unfortunately I managed to soft brick it and somehow I can't go back to stock. Here are all the things I did. I would be happy to get any ideas what to try next:
1. unlocked the bootloader - using asus's official unlock tool
2. flashed twrp recovery - twrp-3.2.1-0-Z01H-20180304.img, using:
adb reboot bootloader
fastboot flash recovery twrp.img
3. updated asus's firmware to the latest official one:
copying UL-Z01H-WW-71.60.139.30.zip onto internal memory
android detects the update and applying it using android
4. Enabling lock pattern at boot (from android settings). Correct pattern required even when booting into recovery
5. Installing supersu via twrp:
adb reboot recovery
installing supersu
wiping caches (the cache partition cannot be wiped)
6. SuperSu working (tested via android)
7. Reading about Magisk. Trying to install magisk via twrp. Magisk's installer complained that the system is not vanilla (due to SuperSu modifications). Have to uninstall SuperSu to return to previous state.
8. Tried uninstalling SuperSu from the program itself (in android). The uninstaller got stuck. The phone become unresponsive and had to reboot.
9. Found a script packaged as an executable zip (to be installed via twrp) that will uninstall SuperSu and return system to pristine state (SuperSu makes a backup of the files it changes before installation) - UPDATE-unSU-signed.zip. Uninstallation worked.
10. Magisk installation still complained about the bootloader. Then things started to go wrong. I unpacked the latest firware UL-Z01H-WW-71.60.139.30.zip, took out boot.img and tried to flash just the bootloader
fastboot flash boot boot.img
11. Upon reboot the phone got stuck at the ASUS logo. Reboot into recovery and into fastboot still works (soft brick). Still shows unlock pattern at boot.
12. I tried flashing the original firmware using TWRP (install a zip). However the installation threw some errors. Unsuccessful.
13. I've tried flashing the system.img from the original firware using fastboot but still it's stuck at the ASUS logo at boot.
fastboot flash system system.img
Here I am stuck. I've read that TWRP cannot install properly the ASUS official firmware but if you flash the original recovery, it can probably flash it properly. Another thing that I think might explain why I cannot get out of the soft brick is that I've enabled the lock pattern at boot, which effectively encrypted some parts of the phone and I have a strong feeling this interferes with the boot process. I will look for a script/installable zip (via twrp) that can remove the lock.
I really need ideas/suggestions before I make something that will turn my phone into a hard brick. Thanks.

What you need to do is flash stock MM recovery from bootloader using "fastboot flash recovery recovery.img"
Since it came with MM preloaded you'll have to install the ROM using stock recovery via adb. It'll take a while, but after that you should upgrade to the latest MM update.
After that, update to any Nougat patch update you wish to receive, because I still haven't figured out yet how to apply them all with @shakalaca's recovery images.
Once you're done, you can install twrp again and flash magisk.
Good luck and hope this helped you

Thanks

Thanks,
I tried to find a stock recovery images but unsuccessful. Can you tell me where to get it from?

Here's a link to Shakalaca's recovery images.
In the Old folder you'll find MM stock recoveries.
https://mega.nz/#F!p90wgAaY!l1JbJilmAUEKTKWu43pT9w!I89QgZpK
Flash 11.40.86.75 recovery
Boot into recovery
Flash 11.40.86.75 stock rom via adb (it'll take a while)
Once it's done, boot into Android.
Download your respective region's latest MM rom.
Send it to your micro sd.
Install it once Android detects the update file.
(It won't work with custom recovery. I tried every recovery Shakalaca has and only those two seem to work)
Once on the latest MM rom install any nougat patch update you wish to apply, because once you have a nougat rom, you can't boot stock recovery. (As far as my testings went)
So if I were you, I'd go for any update after the zenui 4.0 update since it's a bit better looking imo.
After that final update you can flash TWRP to root your phone. I prefer using magisk, since it doesn't modify the system files.
All you need to do is flash magisk and that's it. No need for SuperSU or anything else. And by any means, do NOT wipe your cache partition once you flash TWRP, otherwise you'll get stuck on the Asus logo during boot.
If you wish to retain the "certified" status in google play store's device certification, do NOT go into the play store before installing magisk. Also, don't delete play store data, otherwise you'll lose your previous purchases.
This post was longer than I initially thought it'd be, but I guess this sums it up pretty well.
Good luck

Thanks, I managed to flash 11.40.86.75 and stock ROM using your instructions. I will look now into updating and applying magisk. Just a final question. You mentioned to install Nougat patch update and not a full firmware, but my phone came preloaded with Nougat. Will this be a problem? I installed stock 71.60.139.30 and it worked fine (i was able to boot into twrp).

Hi I managed to flash stock ROM - 71.60.139.30, but after that I can't flash twrp - twrp-3.2.1-0-Z01H-20180304.img. I tried with:
adb reboot bootloader
fastboot flash recovery twrp.img
but when I try to boot into recovery with:
adb reboot recovery
it goes into the stock recovery. Is there something I missed? Do I need to downgrade to flash TWRP?

Quick question: which of these warnings do you get when you boot?
https://www.androidauthority.com/go...rrupted-and-modified-android-software-629180/
Also, did you try power cycling to get it to boot?
And since the version number made such a large jump, I believe they must have changed something internally with the latest update and that it's probably going to be one of the last Nougat updates before Oreo (which was delayed until June).
I still need to update to that version to check it out, but I might reset soon since I was waiting for Oreo to reset.

I have the Orange warning. It looks a bit different but the wording is the same. Yes, i tried powercycling and still I boot into the stock recovery. What can I do now? Is it possible to downgrade? I am not sure if I boot into stock recovery if it will let me flash an older stock ROM.

I read here - https://android.gadgethacks.com/how-to/twrp-101-install-best-custom-recovery-for-android-0179547/
that once you flash twrp Android upon next reboot might overwrite it with the stock recovery. Is that possible?

So, how did you flash TWRP exactly? Using that guide? Or flashed through bootloader?
And to answer your question: yes, it happens sometimes.

Hi, I managed to get around it by directly booting into TWRP from fastboot. Yes, apparently unless I flash some TWRP files to the system partition upon next reboot, the recovery will return to stock. Anyway, I managed to install Magisk and Exposed framework and have been poking with those two for the last couple of days.
The youtube vanced app is great, but I found something that worries me. I can't login to facebook/twitter. I checked and the reason is I can't connect to the facebook.com or twitter.com https sites (even over chrome). I think either:
- I've installed some module which is messing with that
- my rooted phone is hacked
I've installed a module that is meant as ad blocker, that updates the hosts file. However I removed all modules and the problem remains. I really don't wanna start all over again just to check. And even if I reflash and it works, I will not know what caused it and how to fix it myself next time. Do you have any ideas on how to figure out what the problem is?
Regards,

First off, my apologies for this late reply (Been superbusy with school and internship assignments)
Secondly, and that is why I only use magisk. Because once you mess with the host file, depending on what module you install, it can range from tripping safetynet to bootlooping.
So quick question, is it still in this state right now since 9 days ago?
Greetings,
Kevin

[SOLVED] Huawei nova bricked

I folowed this tutorial https://forum.xda-developers.com/nova-plus/development/rom-aospextended-v4-6-t3717372 and all flashing was fine. Due to some inconveniences of this new flashed rom i decided to restore to default rom. I extracted recovery and update.app version Can-L11 B396 i think from firmware finder and flased with adb this recovery. After that, it asked me to do an factory reset, i did it, but it wont boot any of huawei or Aosp Extended. The main problem i have is i can`t acces any more my phone with adb terminal, maybe after flashing the new original recovery usb debbuging reverted to un-enabled. How can I do now? Thanks in advance.

I cant access my phone via adb or twrp recovery. I wonder why. Before flashing a stock recovery all Was fine, adb Was connecting with no problem.

Try to flash the TWRP again with fastboot.
PS: I don't understand how you people end up like this. It never happened to me.

I cant, adb cant be connected to device. Says null operation.

finally i succeed to revert o stock rom. Now i have on About phone CAN-L11C432B397, Emui 5.0 and Android 7.0. One question please, I dont see anymore the Update system tab or something, "Actualizator" on romanian language. Is that normal? How i can check for updates?

You need to install the other zip too which has the word "data_full" at zip's name or something like that.
EDIT: @campeadore, i suggest you to edit the thread name and add "[SOLVED]" at begin and write the way you've fixed your phone (the solution), so it'll help other people who might run into the same problem as you.

I`ll do it as soon i fully resolve the problem. I followed your link and everything went fine at step 1 (Go back to EMUI 4.1 (MM). System is booting, but system update is not working. So, i want to flash EMUI 5, but can-l11c432b330 or can-l11c432b396 cant be updated, around 45% gives an error. The only version who work is can-l11c432b320 but i dont have update_full_CAN-L11_hw_eu, only the first update.zip.

Newer / newest firmware downloaded from Firmware Finder needs to be approved by Huawei and that can take some time. It's failing to install because it wasn't approved. I've read this in past somewhere.
Try B381 or B382 as i've always installed that one when i've went back to EMUI 5.

Yes, i did it now with can-l11c432b330. I think my mistake was trying to flash to EMUI5 with usb cable connected. With cable off all went fine like a charm. Now i do all approved updates with system update. Thank you so much man, really appreciated.

Seeking help: I have a smartphone huawei nova lite plus (TRT LX1) that fails to restart. It goes continuously in a loop. Entering recovery only the first 2 functions come out: wipe wash factory reset and wipe wash partition. Then using eRecovery from PC with the USB cable, proceed up to a certain point and then not continue. I think it's in soft brick. I definitely need the right software for flashing, stock roms and usb drivers. Where can I find them? Many thanks

Lost TWRP after update C100B303 to C100B307 and cannot install again

I had a Media Pad M3 with unlocked bootloader, rooted and TWRP as recovery. As I wanted to update my ROM to BTV-DL09C100B311 I had some problems in TWRP an thought updating step by step would be a good idea. So I downloaded all missing ROMs throught FrimwareFinder and startet with BTV-DL09C100B307_fullOTA.
The installation in TWRP with ADP sideload worked and when I restartet my device a was a bit suprised that the yellow "Bootloader is unlocked - your device is unsecure" message was missing. I restarted again and the message is still missing. I thought OK perhaps I can now install all updates through the EMUI build in process without FirmwareFinder or TWRP.
EMUI downloaded the update and asked me to restart and install. After the restart the install process went to 20% and told me then there was a verification error. When I restarted the tablet again I got a screen similar to the yellow "Bootloader is unlocked - your device is unsecure". The screen is red an told me "Your device has failed verification an may not work properly".
Now I'm stuck. No updates work and TWRP could not be started or installed again.
I tried reinstall TWRP with fasboot (https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232) but I get the error FAILED (remote: "command not allowed"). I tried the newest TWRP mod from https://androidfilehost.com/?w=files&flid=125388 but same error.
Phone and FRP are still unlocked, as shown in FASTBOOT&RESCUE MODE so this is not the cause of the above mentioned fastboot error.
I installed the Android SDK completly and downloaded the newest toolkit (https://developer.android.com/studio/releases/platform-tools) but still get the above error. So I dont think its a driver problem either.
I did not try to unlock the bootloader again. I don't think this makes sense even if I still have the original codes.
I would like to get TWRP back and update the tablet to the newest ROM version. And it would also be nice to know what happened here
Thanks in advance for everyone helping me back on track. I think the first step should be get over the FAILED (remote: "command not allowed") error and install TWRP again.

I got it
Needed to unlock the bootloader again. Even so it throws an error the red starting screen disappeared an I got the usual yellow one back and i could install TWRP.
//Edit
Managed to get to newest Version with this updater: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279

I am also looking for a way to update my rooted M3 (WiFi edition) to the latest available version with security patch line of November.
Now I wonder whether with this updater in your post above this works immediately or if I also have to go through all the difficulties you faced?
Is it possible to install updates with a rooted device with this updater or do you always need to unlock the bootloader again?
Thanks for your help!

Just tried it out now and it worked! Data is still there, homescreen icons are a little bit messed up and root is gone (no problem).
This is great because I was looking now for a long time to find a way to update a rooted M3 with new OTA updats (all the usual way fails).
I used to do it with going back to stock and a factory reset being involved.
Funny that you presented me the solution with your problem.
Glad that you shared it.
Now the only thing I am missing is to install the Xposed Framework on the M3. If you know how to do this let me know (I am using Super SU).

Im happy I could help. I dont use Xposed.

Hi, can you, please, describe this in steps? What I have to do before standard OTA update should work? And when (and how) to open bootloader once more? Thank you very much.

Standard ota updates will not work. If you already have an unlocked bootloader you have to use this method https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279 to manual update your M3 to the newest version.
If you have no unlocked bootloader please check this first https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232
